Specification of Letters Patent.

Patented J an. 5, 1915.

Application filed December 2, 1913. Serial No. 804,250.

To all whom it may concern:

Be it known that I, EDGAR H. ELWELL, a citizen of the United States ofAmerica, residing at Dawson, in the Provinceof Yukon and Dominion ofCanada, have invented new and useful Improvementsin Pliers, of which thefollowing is a specification.

The present invention relates to pliers.

One of the objects of the invention is the construction of a pair ofpliers with a ,removable knife member that embodies both a longitudinaland a transverse cutting edge, whereby a fuse leading to a charge of gunpowder or dynamite may be simultaneously cut transversely and slittedlongitudinally to expose the powder of the fuse without permitting thesaid powder escaping from the fuse.

Another object of the invention is the provision in a pliers of thisclass, of means \fvhereby the cap may be crimped upon the use.

A still further object of the invention is the provision of a plierswhich may be employed for splitting and cutting the ends of an electricconductor Wire to provide the said end with branch wires, as well as forremoving the insulation from thewires.

With the above recited objects in view and others which will appear asthe nature of the invention is more fully understood, the improvementresides in the construction, combination and arrangement of parts setforth in the following specification and falling within the scope of theappended claims.

For the purpose of illustration the accompanying drawing discloses asimple and satisfactory reduction of the improvement to practise, and inwhich drawing:

Figure 1 is a perspective view of a pair of pliers constructed inaccordance with the present invention, Fig. 2 is a central longitudinalsectional view taken through the jaws of the pliers, Fig. 3 is a detailperspective view of one of the jaws, showing the knife and kniferetaining plate or member removed from the jaw, and Fig. 4 .is aperspective view of the second j'aw.

The pliers A comprise the usualtpan' of ivomd members, each of whichincluding a andle and a jaw which is offset from its handle beyond thepivotal connection between the said members, and the handles arenormally swung away from each other through the medium of a flat curvedspring which has one of its ends secured to one of the handles and itsopposite end engaging with the second handle.

One of the handles has its rounded end provided with a rounded member 1,which s employed in the usual manner for forcmg the powder within thecasing of the fuse to provide a pocket or depression for the receptionof the cap after it has been crimped upon the square end of the fuse.

'The jaws, which are designated by the numerals 2 and 3 respectively,are normally spaced away from each other through the medium of thespring above mentioned, and each of the jaws has its inner face of asubstantially similar construction. The inner faces of said jaws areflat for a portion of their length and each of said fiat faces is formedwith a substantially semi-cylindrical transversely arrangedchannel ordepression 4 which, when the jaws are brought together, provide acircular openin'g'between the jaws. The sides of the jaws are projectedin a line with semi-cylindrical openings 4:, and these portions of thejaws are wider than at any other cross section of the said jaws. One ofthe enlargements, upon one side of the jaw 2 is formed by a removableplate or cap 5' which is formed with a semi-cylindrical opening 5 thatis adapted to form a continuation of the semicylindrical depression ofthe said jaw. The top of the member 5, is flat and its sides are reducedfrom the semicylindrical end'5 of the said member, the said ends beinprovided with openings 5 which are a apted to register with vsimilaropenings 5 in the straight side of the jaw 2, the openings 5 beingthreaded and retaining elements, in the nature of screws 5 pass throughthe registering openings 5" and 5 and engage with the threads of theopenings 5. The semi-cylindrical opening 5 of the jaw 2 has the lowerwall or central portion provided ormed with a dovetailed slot or channel13 which extends the entire width of the said jaw. The slot B isadapted. to receive a dove-tailed portion 7 provided upon a knife member8. The member 8 has one of its ends formed with a fiat head 8 which isof a semi-circular formation and its rounded edge sharpened. The head 8may be received within a slot or depressionh provided upon the flat sideof the jaw 2, as illustrated in Fig. 3 of the drawing but such anarrangement is not absolutely necessary, as the reduced ends of themember 5? will give sufficiently when engaged by the heads of the screws5 to spring the said ends tightly against the fiat face of the jaw andthe central and reinforced portion of the said member 5.

The second jaw 3 is provided with. a recess 10, which'extendslongitudinally of the said jaw, and which is adapted-to serve as apocket for the sharpened edge of the head 8 which barely enters the saidrecess. The longitudinal portion of theknife 8 is rounded from its;outer end toward the head 8',

' as clearly illustrated in Figs. 1 and 3 of the drawing, and toaccommodate the portion of the knife at the juncture of the head 8, thechannel or depression 4' of the jaw 3 is provided with a slot 10 whichenters the longitudinal depression or pocket 10.

The jaws adjacent their ends have their inner faces provided with curveddepressions, the walls of which being serrated or otherwise providedwith teeth 6, the purpose of which will presently be set forth.

When the device is employed in connection with a fuse the said fuse isinserted within the cylindrical depression 4 of the jaw 3, and thehandles are forced together to bring the inner faces of the jaws in con-7 tact, and as a consequence, the head 8' will sever the fuse, while theknife 7 will split the fuse. The ends of the jaws which are providedwith the depressions having the teeth 6 are now employed for sustainingan explosive cap, which after being inserted over the square cut of thefuse, is crimped by the said teeth 6, and the splitting .of the said.end of the fuse makes it convenient to touch a match to one of thethreads of the fuse which ignites the powder in the fuse, and the saidignited powder explodes the capwhich is turn explodes the charge ofplyltilamite or gunpowder to which the fuse ea s.

When the device is employed for splitting the ends of an electric wireconductor, the said conductor is inserted within the re cessed ordepressed portions 4 of the jaw 33, and the handles swung together tobring the knife into engagement with the fuse, the said engagementcutting the fuse transversely as well as slittin the samelongitudinally, and the said sit lits the conductor and forms the samewlth two branch wires to which additional connecting wires may beattached; I

From the above description, taken in com insane nection with theaccompanying drawings,

the simplicity of the device as well as the advantages thereof will, itis thought, be perfectly apparent to those skilled in the art to whichsuch inventions appertain without further detailed description.

Having thus described the invention, what I claim is:

1. Pliers for the purpose set forth comprising a pair of pivoted membersincluding spring pressed handles and a jaw provided for each of thehandles, each of the jaws having a flat inner face, the jaws on the saidinner face being provided with alining semi-circular depressionsand'having their sides enlarged to provide extensions which surround thedepressions, one of the said enlargements being removable, thedepression provided upon the jaw with the removable enlargement having aslot, a knifemember adapted to be arranged within the slot, said knifemember including a semicircular head which is arranged transversely ofthe knife proper and which is adapted to abut against the flat side ofthe jaw, means for securing the removable member to the jaw, and thesaid removable member adapted to contact with the outer face of therounded head of the knife. I

' 2. Pliers for the purpose set forth, comprising a pair of pivotedmembers which in clude spring pressed handles and a jaw formed upon eachof the. handles, each of said jaws having an inner fiat face which isrecessed transversely to provide a semi-circular depression, the awshaving their sides provided with enlargements which are also depressed,one of the said enlargements being removable, thejaw provided with theremovable enlargement having the wall of its depression centrally formedwith a lon gitudinally extending dove-tailed slot and its fiat siderecessed, the said recessed portion communicating with both the depression and dove-tailedslot', a knife member having a'dove-tailed endadapted to be inserted within the dove-tailed slot, the said memberbeing provided with a transverselyarranged head which is adapted to bereceived within the depression in the side of the jaw, and means comrisingremovable elements for securing t e removable enlargement to thejaw.

3. Pliers comprising a pair of pivoted members including spring pressedhandles and a jaw formed upon each of the handles, each of said jawshaving an inner flat face which is recessed to provide a transversesemi-circular depression, the opposite faces of the jaws havingextensions :which surround their depressions to provide extensions forthe said depressions, the said depressions adapted to register when thejaws are brou ht together, each of the jaws be ingprovided withlongitudinally extending slots, eknife member secured longitudinelly ofand centrally within one of the depressions, aknife heed having a curvededge and secured to one end of the knife member transversely thereof,the registering depression of the other jaw adapted to receive the lmifemember and .its head when the jews are closed, and the reduced ends ofthe jaws having areuate' depressions which are toothed. In testimonywhereof I affix my signature in presence of two witnesses.
